The successor to the GPUs powering Intel's new Ice Lake-U series has appeared on GFXBench, and boy is it currently a stinker. The GPU, identified as the UHD Graphics Gen12, performed miserably in benchmarks. However, as it is not slated to arrive for another eighteen months, we are certainly looking at an early engineering sample.

I'm not surprised, hence why I plan to buy in at ice lake. It'll probably take a few years for all the software to properly implement all the optimizations for both Intel and Developers.
